Low Power, 5V/3.3V, μP Reset, Active LOW, Open-Drain Output
March 2005
General Description
The ASM1233D-L/1233D/1233M are voltage supervisors with
low-power, 5/3.3V μP Reset, with an active LOW, open-drain
output. Maximum supply current over temperature is 15μA for
3.3V devices and 20μA for 5V devices.
The ASM1233D-L/1233D/1233M generates an active LOW
reset signal whenever the monitored supply is out of tolerance.
A precision reference and comparator circuit monitors power
supply (V
CC
) level. The tolerance are 5%,10% and 15%. When
an out-of-tolerance condition is detected, an internal power-fail
signal is generated which forces an active LOW reset signal.
After V
CC
returns to an in-tolerance condition, the reset signal
remains active for 350ms to allow the power supply and system
microprocessor to stabilize.
The ASM1233D-L/1233D/1233M is designed with an open-
drain output stage and operates over the extended industrial
temperature range. These devices are available in compact
SOT-223, SO-8 and TO-92 packages.
Other low power products in this family include ASM1810/11/
12/15/16/17.
